Some of California's strongest storms in years moved through the state in the winter of 2017, bringing drought-busting rain, flooding and sights that Californians hadn't seen for years.

Most of the precipitation was ushered into the region by a weather phenomenon called an atmospheric river -- waves of moisture that move north from tropical areas and over the West Coast. The freight train of rain has been good for California's drought, but also led to dangerous flooding and severe weather.
